A rough dry-in is achieved once ZIP System™ flashing tape, with a minimum width of 3-3/ 4”, is properly installed and window and door openings have been flashed. For walls, ZIP System sheathing functions as a combination wall sheathing with the overlay that functions as an air barrier and whose water resistance is equivalent to a Type II water-resistive barrier (WRB). For roofs, ZIP System sheathing functions as the structural decking with an overlay that eliminates the need for felt underlayment (see page 43 for limitations related to roof pitch). For wall or roof coverings that require multiple layers of WRB or underlayment, ZIP System sheathing and flashing tapes are intended to replace only the first layer. ZIP System sheathing can be used with a range of exterior claddings and roof coverings. Wall coverings that can be used with ZIP System sheathing include brick, vinyl, stone, fiber cement, wood (shake, shingles and lap siding), traditional hard coat stucco and EIFS* applications. Approved roof coverings include asphalt-fiberglass shingles, metal tiles and panels, clay/ concrete tiles, slate/ slate-type shingles and wood shakes/ shingles. Follow all cladding and roof covering manufacturer’s installation instructions. ZIP System sheathing may be used for roofs and walls in Type V construction, in Type III construction as roof sheathing only, and other construction permitted under the International Residential Code ® (IRC) and International Building Code ® (IBC). *Only mechanically attached exterior insulation and finish system (EIFS) claddings are covered by ZIP System warranties. 7 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® SHEATHING / / NOTES & LIMITATIONS When used on roof slopes less than 2:12, ZIP System ® sheathing panels may act as the structural decking only. Do not use abutted against stone or masonry without providing a minimum of a 1/ 2" gap. Do not install ZIP System ™ flashing tape or stretch tape in temperatures less than 0 degrees Fahrenheit. ZIP System products are not recommended for manufactured housing projects built under the federal building code administered by the U.S. Department of Housing and Urban Development (HUD). HEW products are warranted solely under IRC and IBC governed projects. Do not use ZIP System flashing tape or stretch tape to permanently seal around circular roof projections (plumbing vents, pipes, etc.) ZIP System ® sheathing should be covered with the finished roof covering or exterior wall cladding within 180 days of installation. After 180 days of exposure, a mechanically fastened WRB or underlayment must be installed over the ZIP System sheathing. Finished roof and exterior cladding products should be installed per the manufacturer’s installation instructions. 8 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® SHEATHING / / NOTES & LIMITATIONS When original roof coverings or wall claddings are removed, the roof or wall must be covered with an additional roofing underlayment or WRB prior to installation of the new roof covering or wall cladding. In cladding systems requiring multiple layers of water- resistive barriers, such as traditional hard-coat stucco, ZIP System ® sheathing is intended to replace only the first layer. Therefore, at least one layer of mechanically fastened WRB must be installed over the ZIP System sheathing prior to installing hard-coat stucco or adhered stone. See pages 34-37 for more information. ZIP System ™ flashing tape is not recognized as a replacement for rigid, metal or other through wall flashings prescribed by others. Where rigid flashings are present, ZIP System ™ flashing tape or liquid flash can be used as a transition from the ZIP System sheathing surface to the rigid flashing. WALLS: Do not apply a fluid-applied WRB or self-adhered WRB over the entire ZIP System wall assembly. When transitioning between dissimilar sheathing materials, transition onto the ZIP System no more than 12 inches. ROOF: Do not apply a fluid-applied coating over ZIP System sheathing in a roof application. Ice barriers can be installed over ZIP System sheathing in a roof application. 9 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® SHEATHING / / NOTES & LIMITATIONS WET BLOWN CELLULOSE INSULATION In addition to following manufacturer installation instructions, we recommend a maximum cellulose moisture content of the cellulose of less than 25% measured at the inside surface of the ZIP System ® sheathing panel before closing the wall cavity. SECONDARY COATINGS Do not apply secondary coatings or treatments to ZIP System sheathing panels with the exception of the following: Field applied water-soluble borate insecticide or fungicide treatments applied to the non-overlay side of the panel. See technical tip, “Termite Treatments on ZIP System sheathing, ” at huberwood.com for more information. Permeable laminated radiant barrier foil or paint. For a radiant barrier foil or coating to be considered permeable, it must have an applied permeance of five perms or greater as tested by the ASTM E 96 wet cup standard. For a radiant foil, the permeance evaluation would include any adhesive and/ or backer used to laminate a foil. For a radiant paint/ coating, the permeance evaluation should be conducted at the applied thickness of the paint/ coating. 1 2 10 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® SHEATHING / / STORAGE & HANDLING Set panel stack on three supports (stickers) to keep off the ground. Outdoors, cover panels loosely with waterproof protective material. Anchor covers on top of the stack, but keep away from sides and bottom to assure good air circulation. In high moisture environments, cut banding on the panel stack to prevent edge damage. ZIP System ™ flashing tape and stretch tape are pressure sensitive tapes that must be rolled with a rubber-faced roller in order to achieve maximum bond to the panel. Exterior foam insulation (XPS, EPS etc.) can be mechanically installed with button caps, staples etc. over ZIP System ® sheathing. Exterior foam cannot be adhesively attached over ZIP System sheathing. 11 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® SHEATHING / / PANEL SIZES The green ZIP System ® sheathing denotes a 7/ 16-inch panel while the sienna ZIP System sheathing denotes either a 1/ 2-inch or 5/ 8-inch panel.

SEALANTS For sealant compatibility with ZIP System sheathing, ZIP System flashing tape, ZIP System ™ stretch tape, and ZIP System ™ liquid flash, please refer to the Technical Tip “Window and Door Sealant Compatibility with ZIP System Sheathing and Accessories” at huberwood.com ALLOWABLE SHEAR CAPACITIES ZIP System sheathing panels are DOC PS 2 compliant wood structural panels. For more information on designing shear walls with ZIP System sheathing, see Technical Tip “Shear Capacity and Wood Structural Panels” at huberwood.com 14 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® SHEATHING / / GENERAL INFORMATION & COMPATIBILITY FLASHINGS - TAPES Minimum 3-3/ 4” wide ZIP System ™ flashing tape must be used where two ZIP System ® panels come together to create a panel joint at inside corners, outside corners and in the same plane; however, other code approved flashing tapes that satisfy AAMA-711 or AC-148 can be used to flash rough openings, penetrations, and fenestrations. FLASHINGS – FLUID APPLIED ZIP System ™ liquid flash can be used in lieu of ZIP System flashing tape where two ZIP System panels come together to create a panel joint at inside corners, outside corners and in the same plane. Other code approved liquid applied flashing membranes that satisfy AAMA- 714 can be used to flash penetrations and fenestrations. When using fluid applied flashing products over 3-3/ 4” wide ZIP System flashing tape refer to Technical Tip “Compatibility of ZIP System Flashing Tape with ZIP System Liquid Flash”*. WRINKLES IN THE TAPE Rolling ZIP System flashing tape will significantly reduce the possibility that the tape will wrinkle. If wrinkles occur, first try to roll the wrinkles out with a rubber headed roller. This should help eliminate wrinkles or “fish mouths” (large wrinkles that are avenues for water to get to the seam). If rolling the tape does not remove the fish mouths, remove that section of tape, replace it with a new piece, then overlap the existing tape by at least three inches. Alternatively, with the fish mouth still in place, put another piece of flashing tape over the fish mouth so that it is completed covered. ROLL THE TAPE. *ZIP System flashing tape should not be installed over ZIP System liquid flash 15 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® SHEATHING / / GENERAL INFORMATION & COMPATIBILITY PARAPET WALL TERMINATION ZIP System ® sheathing used as parapet wall sheathing is compatible with single-ply roofing membrane terminations. It is recommended to transition from the top of the single-ply roofing membrane to the surface of ZIP System sheathing with a metal flashing. Transition the metal flashing back to the ZIP System sheathing using ZIP System ™ flashing tape or liquid flash. Refer to roofing membrane manufacturer’s installation instructions for proper installation requirements. Please note, a polyurethane or solvent based adhesive should be used when adhering the built-up membrane to ZIP System sheathing. All panel seams should be taped prior to installing the built-up membrane over ZIP System sheathing. TOOLS Common Recommended - Pneumatic nail gun - Flush nail collars - Framing hammer - Air line regulators - Air compressor - Speed square - Tape Roller - PPE 16 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® WALL SHEATHING / / GENERAL INSTALLATION - WALL The following installation steps are presented as a general outline of the installation process. These are manufacturer installation recommendations – please visit huberwood.com for a library of flashing and installation details. You are fully and solely responsible for all safety requirements. Good construction and safety practices should be followed at all times. For optimal air leakage reduction, all non-taped edges of the panels can be caulked, gasketed or sealed with weather stripping material. Take special care to remove any voids and/ or trapped air under the panels. ZIP SYSTEM ® WALL SHEATHING / / PANEL ORIENTATION AND SPACING Install ZIP System ® sheathing panels positioned with the water-resistive barrier facing outside. The panels may be installed with the long side of the panel oriented either horizontally or vertically to the framing members. Walls that are designed to resist lateral shear forces and sheathed with wood structural panels typically require solid framing or blocking behind all panel edges. Add blocking at horizontal joints when walls are designated for bracing or as a shear wall. 17 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® WALL SHEATHING / / PANEL ORIENTATION AND SPACING - 1/ 8" spacing between square edges of all adjacent panels is recommended in accordance with industry standards for wood sheathing installation. - ZIP System ® sheathing’s unique edge profiles are designed to accommodate incremental panel expansion and does not require manual gapping along the 8' edges. - Maintain 1/ 8" space where 8' panel edges meet 4' panel edges. Unique edge profile does not provide the full 1/ 8" recommended space in this situation and must be done manually. - Maintain 1/ 8" space where 4' edges meet. Unique edge profile is on 8' edges only. 1/ 8” space must be done manually on 4’ edges. - For information on vertical panel installations, go to huberwood.com learn more. ZIP SYSTEM ® WALL SHEATHING / / FASTENING Fasten the panels to the framing members with code approved fasteners. Space fasteners 6" o.c. along supported edges and 12" o.c. at intermediate supports, unless otherwise specified by local code or the designer of record. It’s the responsibility of the general contractor to verify proper fastener type and spacing prior to installation. Apply fasteners a minimum 3/ 8" from panel edges. ZIP System sheathing does not have proprietary shear values and has the same shear values of Structural 1* OSB or plywood of equivalent thickness. 4' edge meets 4' edge 8' edge meets 4' edge 8' edge meets 8' edge 18 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® WALL SHEATHING / / OVERDRIVEN FASTENERS Steps must be taken to seal fastener penetrations when: 1) a fastener penetrates more than halfway through the wood portion of the panel; or 2) a panel fastener misses the framing and results in a “shiner.” Fasteners that penetrate more than halfway through the wood portion of the panel must be covered with a ZIP System™ tape or ZIP System™ liquid flash. Shiners must be removed and resulting holes covered with a ZIP System tape or ZIP System liquid flash. Failure to seal these types of fastener penetrations as required will void the ZIP System sheathing warranty. We recommend the head of the fastener is installed flush to the surface of the ZIP System panel. Flush fastener placement is best achieved by properly setting the nail gun air compressor to the manufacturer’s recommended setting or using in-line pressure regulators. Many nail guns have depth control adjustments to ensure fasteners are driven flush. For tools that do not have a depth control adjustment feature, we recommend fitting a flush drive attachment collar on the end of the gun to help limit fastener embedment depth. Underdriven fasteners should be hand-driven flush before taping. ZIP SYSTEM ® WALL SHEATHING / / OPTIONAL FASTENER TREATMENT For those looking for an extra layer of protection to elevate their build above the base requirements for the ZIP System wall sheathing panels, ZIP System liquid flash can be installed on fastener heads after the ZIP System seam tape is installed. This approach can be done with all wall claddings including hard-coat stucco and adhered stone. 19 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® WALL SHEATHING / / TAPING Apply minimum 3-3/ 4” ZIP System ™ flashing tape after all ZIP System ® sheathing panels are fully fastened to wall-framing members. ZIP System flashing tape uses an acrylic adhesive that requires pressure from a rubber headed roller for an adequate seal. REMEMBER TO ALWAYS: Use ZIP System flashing tape with a minimum width of 3-3/ 4”, or ZIP System liquid flash, to seal the seams of ZIP System sheathing panels, including at all inside and outside corners. Ensure that the panel surface is dry and free of sawdust and dirt prior to taping. Ensure that the tape is centered over the seam within +/ - 1/ 2" to provide adequate coverage. Wherever tape splices occur at a horizontal or vertical seam, create an overlapping splice of at least 3" (see next page). At T-joints, tape pieces should overlap by at least 1" (see next page). Tape over any areas of the panel that are damaged during construction. Use a rubber headed roller to apply pressure on the tape and smooth out any wrinkles. 20 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® WALL SHEATHING / / TAPING INSIDE CORNER: Use ZIP System ™ flashing tape with a minimum width of 3-3/ 4” at all inside corners. It is helpful to cut a manageable length of ZIP System flashing tape and hold the ends in the middle using only your index fingers and thumbs. Slightly pulling both ends of the tape causes the tape edges to naturally curl inward. With tape in tension, place it in the center of the inside corner. Repeat as you go up the wall. Roll the tape. OUTSIDE CORNER: Use ZIP System flashing tape with a minimum width of 3-3/ 4” for outside corners. Start by working on a single plane using a length of tape that feels manageable. To fold the tape onto the other plane, use your hands to push the tape around the corner. It is recommended to start at the top of the tape and work your way down when pushing the tape on to the other plane. Roll the tape. 21 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® WALL SHEATHING / / FLASHING DETAIL AND CLADDING NOTES When it comes to installing ZIP System ® sheathing, Huber Engineered Woods (HEW) requires the use ZIP System ™ flashing tape with a minimum width of 3-3/ 4”, or ZIP System ™ liquid flash, to seal the seams of ZIP System sheathing panels, including at all inside and outside corners.

ZIP SYSTEM ® ROOF SHEATHING / / ROOF COVERINGS ROOF COVERINGS ZIP System sheathing is code-recognized sheathing and underlayment and is approved for use with following roof coverings: Asphalt-fiberglass Shingles, Slate and Slate-type Shingle, Wood Shingles and Wood Shakes, Metal Roofs (shingles and panels), and Clay/ Concrete Tiles. When installing roof coverings, follow applicable building codes, manufacturer’s suggested instructions and applicable third-party guidance. Some roof coverings require a slip-sheet or interlayment in addition to conventional roofing underlayment. All ZIP System panel seams should be taped prior to installing slip sheets or interlayment when required. 41 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® ROOF SHEATHING / / GENERAL INSTALLATION - ROOF The following installation steps are presented as a general outline of the installation process. These are manufacturer installation recommendations – please visit huberwood.com for a library of flashing and installation details. You are fully and solely responsible for all safety requirements. Good construction and safety practices should be followed at all times. After establishing compliance with all OSHA and local code safety guidelines, ensure that the panel surface is dry and clean of any nails, sawdust, or other debris or protrusions prior to installing or walking on the panels. ZIP SYSTEM ® ROOF SHEATHING / / PANEL ORIENTATION AND SPACING PANEL SPACING Install ZIP System ® sheathing panels with the overlay facing outside towards the sky. Per industry standards for wood sheathing, a 1/ 8 inch spacing between panel edges of adjacent panels is recommended. ZIP System ® sheathing panels have a unique edge profile designed to self-space 1/ 8 inch on the 8-foot edges. The 4-foot ends of the panels have a square edge profile which will require the 1/ 8 inch spacing to be manually applied. 4' edge meets 4' edge 8' edge meets 4' edge 8' edge meets 8' edge 42 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 PANEL ORIENTATION Ensure that ZIP System ® panels span at least three framing members. The 4’ edge of the panel must be support by a framing member. The long edge (8’) should be oriented perpendicular to the framing members, and panels should be installed with the 4’ edge seams staggered a minimum of 24” FASTENERS Using code approved fasteners, attach the ZIP System sheathing panel to framing members following the fastener pattern specified by the designer of record or local building code. Apply the fasteners a minimum 3/ 8” from the panel edges. It’s the responsibility of the general contractor to verify proper fastener type and spacing prior to installation. We recommend the head of the fastener is installed flush to the surface of the ZIP System panel. Flush fastener placement is best achieved by properly setting the nail gun air compressor to the manufacturer’s recommended setting or using in-line pressure regulators. Many nail guns have depth control adjustments to ensure fasteners are driven flush. For tools that do not have a depth control adjustment feature, we recommend fitting a flush drive attachment collar on the end of the gun to help limit fastener embedment depth. Underdriven fasteners should be hand-driven flush before taping. 43 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® ROOF SHEATHING / / ROOF PITCH ROOF PITCH ZIP System ® sheathing is intended to replace the structural decking and single layer of underlayment as required by the IRC and IBC when a roof pitch is 4:12 or greater. When the roof pitch is at or between 2:12 - 4:12, the IRC and IBC require two layers of underlayment. ZIP System sheathing only replaces one of the two required layers of underlayment; therefore, one additional layer of underlayment is needed to satisfy the building code. When the roof pitch is less than 2:12, ZIP System sheathing panels can be used, but can only act as the structural decking. When roof pitch is less than 2:12, a low-slope roofing membrane is to be installed. ZIP SYSTEM ® ROOF SHEATHING / / TAPING TAPING Ensure that the panel surfaces are dry and free of any nails, sawdust, debris, or protrusions. Apply minimum 3-3/ 4” ZIP System ™ flashing tape after all ZIP System ® sheathing panels are fully fastened to roof- framing members. Only ZIP System flashing tape should be used to seal the seams of ZIP System panels. Avoid stepping on tape in high temperature environments. Roll the ZIP System flashing tape with a rubber headed roller. NOTE: For optimal air leakage reduction, all untaped edges of the panels can be caulked, gasketed or sealed with a weather stripping material. 44 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® ROOF SHEATHING / / COMMON DETAIL ICE BARRIERS Self-adhered ice barriers, such as ZIP System ™ peel and stick underlayment, may be required by local building code, the authority having jurisdiction or the designer of record. ZIP System ® sheathing and flashing tape are not considered a replacement for self-adhering ice barriers. Therefore, when self-adhering ice barriers are required, they should be installed in addition to ZIP System sheathing and flashing tape. OPTIONAL: install a piece of ZIP System ™ flashing tape over the top edge of the ice barrier. FLASHINGS - ROOF When flashing details such as drip edge, step flashing or crickets, use ZIP System flashing tape, flashing tapes satisfying AAMA 711 or AC148, fluid applied flashing satisfying AAMA 714 or cold applied asphalt roof cement that satisfies ASTM D4586 Type I or II. 45 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® ROOF SHEATHING / / COMMON DETAIL H-CLIPS Huber Engineered Woods requires panel edge support for 7/ 16" ZIP System ® sheathing installed on roof supports spaced more than 16" on center. Panel edge support might be blocking, tongue-and- groove* edges or panel edge clips (H-clips). When taping over H-clips, it is important to make sure that the tape is centered and adequate pressure is applied on all sides of the clip to ensure a proper seal. It should be noted that the use of edge support (H-clips, blocking, tongue-and-groove* edges, etc.) does not increase the maximum allowable load on a roof for a given truss or rafter spacing. *Tongue-and-groove edge profile only offered on 5/ 8” ZIP System sheathing. 46 ZIP SYSTEM ® SHEATHING AND TAPE INSTALLATION MANUAL HUB 81670 REV 02/ 06/ 2025 ZIP SYSTEM ® ROOF SHEATHING / / COMMON DETAIL ALTERNATIVE DETAILS / / TOE BOARD STEP 1: Often, toe boards are used to assist the installer during the installation of the panels or other roofing materials.
